STREET-GAGE.

Specification of Letters Patent.

Patented Mar. 29, 1910.

Application filed June 5, 1909. Serial No. 500,455.

To all whom it may concern:

Be it known that I, PATRICK RoUoHnN, a citizen of the United States, anda resident of Fond du Lac, in the county of Fond du Lac and State ofIVisconsin, have invented a certain new and useful Street-Gage, of whichthe following is a full, clear, and exact description.

The principal objects which the present invention has in view are: toprovide a mechanical device to be used as a detector for inequalities ingrading of a street pavement; to provide a device of the characterspecified wherein the height of the crown of a paved street may bemechanically adjusted; to provide a contrivance of the characterspecified, which is movably and guidably mounted on the street, to bereadily shifted over the surface of the street; and to provide amechanical contrivance for the purpose mentioned, capable of beingadjusted to varying street widths.

One embodiment of the invention is disclosed in the constructionillustrated in the accompanying drawings, wherein like characters ofreference indicate corresponding parts in all the views.

Figure 1 is a perspective view of a gage constructed in conformity withthe present invention, showing the same as in operative position on thesurface of a street; Fig. 2 is a horizontal section taken on the line2-2 in Fig. 1; Fig. 3 is a vertical section taken on the line 33 in Fig.1; Fig. 41 is an enlarged detail, partly cut away to show theconstruction of the adjusting device for setting the gage; Fig. 5 is ahorizontal section, taken on the line 5-5 in Fig. 4:; and Fig. 6 is adetail view of the mounting and housing of the carrying wheels for thegage.

The gage is built in two sections hingedly secured at 7, the hinge 7being rigidly mounted upon laterally extended flanges of short masts 8.The masts 8 are formed from the two sections of angle iron, as shownparticularly in Figs. 1 and 2 of the drawings. The mast sections aredisposed vertically as shown, with one of the flanges of the angle ironfrom which said sections are formed being extended parallel with forms9. The remaining flanges are mounted in the manner shown in Fig. 2,where they are brought together back to back, and when in operativeposition are secured by bolts and nuts 10. One of the two abuttedflanges of the masts 8 is provided with an extension 11, to support atie rod 12, which is secured to the forms 9 by being bolted thereto at13. When the tie rod 12 is thus bolted into position, and extended overthe extension 11, the forms which are secured to the mast sections bybolts 1 1 are held rigidly in an outstretched position such as shown inFig. 1 of the drawings. The forms 9 are further secured to the masts 8by truss rods 15. The rods 15 are bifurcated and secured to the forms bybolts 16, and at the top are passed through eared brackets 17. Thebrackets 17 may be adjusted lengthwise on the rods 15, so that thetension on the rods may be increased or diminished. This furthercompensates for any variation 1n the angle at which the forms 9 areextended from the masts 8. To provide for the variation of the angle ofthe extension of the forms 9, I increase the size of the bolt holes, orprovide a slit if need be, in the forms 9 or in the flange of the mastto which they are secured, and wherein are mounted the bolts 14. I havenot shown this construction in the drawings, for the reason that thevariation is so slight at this point, as to be practically impossible ofillustration 1n drawings such as accompany the present application.

The forms 9 are inserted within box-like end pieces 18, made from anysuitable metal, perforated as at 19 to receive bolts 20, the forms 9being provided with bolt holes to receive the bolts 20. \Vith such aconstruction, the end pieces 18 may be extended farther upon, or drawnout from, the forms 9. In practice, I construct the ends about three orfour feet in length, which results in adjustable expansion, permissibleto the gage, of six or eight feet. I am not limited to the length of theend pieces, and should the extension prove inadequate, I may readilyadopt others of greater length. The end pieces 18 are rigidly secured toupright arms 21, upon which are fixedly secured brackets 22 Fig. 41through a flange of which are passed bolts 23. The arms 21 are provided,with a. series of perforations to receive the bolts 2;), so that thebrackets 22 may be adjusted lengthwise upon the arms 21, therebyaccommodating an extension of the gage members to a greater depth thanthat illustrated in Fig. 1.

The brackets are provided with an enlarged end 2% Fig. 5 in which isprovided a vertical screw threaded perforation, to receive in threadedengagement, an adjusting screw 25, provided with a hand wheel 26 bywhich the said screw is turned, and is also provided with a collar 27.The hand wheel is provided with an enlarged hub 28, and between the hub28 and the collar 27 the ca 29 of a pipe standard 30 is held. The pipestandard 30 constructed from suitable piping, and is threaded at the topand bottom as shown particularly in Fig. 1- of the draw ings.

At the top the threads receive the cap 29, while at the bottom they areinserted within a screw threaded perforation in a truck bar 31. Eachpipe standard 30 is of an internal diameter such as will neatly fit theenlarged end 24: of the bracket and is slotted lengthwise to pass theweb of the bracket 22, said slot being shown in Figs. 1 and 5, where itis indicated by the numeral TV hen the screw 25 is in threadedengagement with the bracket 22, as shown in Fig. a of the drawings,wherein the hub 28 rests upon one side of the cap 29, and the collar 27is secured rigidly to the screw 25 on the under side of the cap 29, anymovement on the part of the screw 25 causes the bracket 22 to rise orfall in the standard 30, to rest upon the surface of the street. Theweight of the forms 9 is carried upon the brackets 22 and the screwsMounted upon the brackets 22 by means of bolts 33, are the clamping aws34 provided with solid body portions formed to fit snugly over the pipestandard 30. At the outer extremity the clamping aws 3 1 are held inoperative relation by bolts 35. V

The operation of the clamping jaws 3st and the bolts 33 and 35 is asfollows: When adjusting the forms to the grade furnished by theengineers, the screw 25 has been turned to cause the bracket 22 totravel up or down on the standard 30, and having arrived at the properheight, the bolts and 235 are drawn taut by the nuts with which they areprovided, causing the body portions of the clamps 34: to bind hard uponthe standard 30 and the sides of the arms 21, and thus render itimpossible or exceedingly difficult to shift the position of the saidarms, and the standard 30. A slight turn, or at most two turns, of thenuts upon these bolts, will at any time release the clamp upon thestandard 30 sufliciently to permit the screws 25 to be rotated to raiseor lower the arms 21 and the forms 9.

The truck bar 31 is extended transversely to the stretch of the forms 9and is provided with rollers 36. mounted in the extreme ends of thetruck bars 31. The rollers 36 are so disposed that they travellengthwise of the street being graded.

Vith the gage thus constructed and mounted, it will be seen that it maybe moved lengthwise of the street upon the rollers 36 with ease.

Extended crosswise from the truck bars 31 are fender bars 3'7 providedwith rollers 38, pivotally mounted in the outer end there of. The fenderbars 37 are suitably provided with a series of bolt holes 39, throughwhich a bolt 10 passes, and by which the fender bars are secured to thetruck bars By means of these series of holes, the fender bars 37 may beadjusted to lengthen or shorten their projection from the truck bars 31.The fender bars 37 are each pro vided. with a vertical extension 41,horizontally extended from which is a wheel 42. By this construction,should the gage line be set back of a guide member, the fender bars 37may be placed over the guide members and the wheels 42 rest against theback of said guide member.

The outer sides of the standard 30 are provided with gage markings 43,by means of which the engineer in charge may set his instructions sothat the mechanic in charge of the grading being done upon the street,can readily adjust the standards 30, to comply with the specificationsof the engineer.

A feature in the present construction which has been worked outcarefully is to provide a construction which may be readily and quicklyknocked down. The masts 8 may be disconnected from the forms 9 byremoving the bolts 14 and the brackets 17. The tie rod 12 is removedfrom the forms by releasing the bolts 13 and the truss rods 15 areremoved from the forms by releasing the bolts 16. The forms arewithdrawn from the end pieces 18 by removing the bolts 20 andwithdrawing them from the said end pieces. In this condition, the masts8 and the rods 15 and 12 and the two forms 9 are in a separatedcondition and may be packed together. The end pieces 18 are disn'lantledby withdrawing the standard 30 from engagement with the bracket 22,which is accomplished by removing the cap 29 from the said standard. Theknockdown condition of the end pieces 18 would, in this condition, leavethe truck bar 31 and the parts connected therewith, including thestandard 30, in one part. while the ends 18 with the arms 21 wouldconstitute the other part.

With an apparatus constructed as herein described, and as shown in theaccompanying drawings, the operation is as follows: The form having hadmounted thereon the end pieces 18 and connected parts, having beensuspended from the masts 8, as shown in Fig. 1 of the drawings, the endpieces 18 are adjusted laterally on the forms 9 until the wheels 38 onthe fenders 3'7 strike against the curb, or guiding member marking thefull width of the street. In this po sition, the apparatus is movedalong the length of the street, the forms 9 constituting the gage forthe surface thereof. If the gage is to be used to determine thethickness of the pavement, this is accomplished by setting the forms upon the standards 30 to the required thickness for the body of thepavement, it being presumed that the wheels 35 are tracking in thegutter, or on the foundation of the pavement. As the apparatus is movedfrom point to point over the surface of the pavement, it is easy todetect any areas which are out of true.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
